This application is continuation of U.S. patent application Ser. No. 16/117,310, filed Aug. 30, 2018, which is continuation of U.S. patent application Ser. No. 14/781,857, filed Oct. 1, 2015, which is a national stage application under 35 U.S.C. § 371 of International Application No. PCT/EP2014/056498, filed Apr. 1, 2014, which claims the benefit of European Patent Application No. 13305432.0, filed Apr. 3, 2013, European Patent Application No. 13290188.5, filed Aug. 8, 2013, and European Patent Application No. 13306412.1, filed Oct. 15, 2013 the disclosures of each of which are explicitly incorporated by reference herein.

The application relates to an aqueous pharmaceutical formulation for use in the treatment of Type I or Type II Diabetes Mellitus, wherein the treatment reduces the risk of nocturnal hypoglycemia, said formulation comprising 200-1000 U/mL [equimolar to 200-1000 IU human insulin] of insulin glargine, with the proviso that the concentration of said formulation is not 684 U/mL of insulin glargine.

Insulin glargine is 31^(B)-32^(B)-Di-Arg human insulin, an analogue of human insulin, with further substitution of asparagine in position A21 by glycine.

WO2008/013938 A2 discloses an aqueous pharmaceutical formulation comprising insulin glargine at a concentration of 684 U/mL.

Metformin is a biguanide hypoglycemic agent used in the treatment of non-insulin-dependent diabetes mellitus (diabetes mellitus type 2) not responding to dietary modification. Metformin improves glycemic control by improving insulin sensitivity and decreasing intestinal absorption of glucose. Metformin is usually administered orally.

Lantus® is an insulin product containing insulin glargine providing 24 hour basal insulin supply after single dose subcutaneous injection.

The glucodynamic effect of Lantus® is distinguished from other currently marketed insulin products by virtue of a delayed and predictable absorption of insulin glargine from the subcutaneous injection site resulting in a smooth, 24 hour time-concentration and action profile without a definite peak. Lantus® was developed to meet the medical need for a long-acting insulin product that can be administered as a single daily injection to yield normal or near-normal blood glucose control with a basal insulin profile that is as smooth as possible over a 24-hour period. Such a preparation provides good control of blood glucose all day, while minimizing the tendency to produce hypoglycemia seen with other insulin preparations with a more definite “peak” effect.

A considerable number of patients, in particular those with increased insulin resistance due to obesity, use large doses to control blood glucose. For example, a dose of 100 U requires injection of 1 mL Lantus® U100, which may confer some discomfort; each mL Lantus® U100 contains 100 U (3.6378 mg) insulin glargine. To reduce the volume of injection, a formulation containing 300 U insulin glargine per mL has been developed.

The purpose of the multicenter, randomized, open-label, parallel-group study as described in Example 1 was to compare the efficacy and safety of insulin glargine U300 with that of Lantus, both given once-daily subcutaneous (S.C.) as part of a basal-bolus insulin regimen in patients with type 2 diabetes. Patients with type 2 diabetes and glycated hemoglobin A1c (HbA1c) in the range of 7% to 10% injecting at least 42 U Lantus U100 or equivalents of neutral protamine Hagedorn (NPH) insulin in a basal plus mealtime insulin regimen were eligible for the study. These patients on relative high doses of basal insulin benefited from the lower injection volume of a U300 insulin formulation as compared with U100 formulations.

Each mL insulin glargine U300 contains 300 U (10.9134 mg) insulin glargine. This formulation would allow patients to inject the same number of units of insulin glargine at one third the volume of injection. This formulation is also termed herein as HOE901-U300.

In the study described in Example 1, patients were stratified by their HbA1c (<8.0%; 8.0%). The primary efficacy analysis tested non-inferiority of insulin glargine U300 compared to Lantus in terms of change of HbA1c from baseline to endpoint (scheduled at month 6; non-inferiority margin 0.4% HbA1c units). HbA1c reflects the average glycemia over several months and has strong predictive value for diabetes complications. The 6-months duration of study treatment is considered to be sufficient for achieving steady state conditions with insulin glargine U300 after changing over from Lantus or NPH insulin enabling an adequate assessment of time-dependent changes in HbA1c and the concomitant risk of hypoglycemia.

Main secondary endpoints included nocturnal hypoglycemia. Hypoglycemia is the critical limiting factor in the glycemic management of diabetes in both the short and long term. Despite steady improvements in the glycemic management of diabetes, population-based data indicate that hypoglycemia continues to be a major problem for people with both type 1 and type 2 diabetes (American diabetes association, workgroup on hypoglycemia: Defining and Reporting Hypoglycemia in Diabetes. Diabetes Care 28(5), 2005, 1245-1249).

In the study described in Example 1, it was surprisingly found that by treatment of diabetes type 2 patients with an insulin glargine U300 formulation, the risk of a nocturnal hypoglycemic event can be significantly reduced compared with the treatment with Lantus® U100. The incidence of patients with at least one nocturnal severe and/or confirmed hypoglycemia between start of Week 9 and Month 6 was lower in the U300 group [136/404 (33.7%)] than in the Lantus group [180/400 (45.0%)] (see Table 6). Superiority of U300 versus Lantus was shown with a relative risk of 0.75 (95% CI [0.63, 0.89]) (p=0.0010).

Example 2 describes a clinical trial comparing the efficacy and safety of an insulin glargine U300 (HOE901-U300) formulation and Lantus® U 100, both in combination with oral antihyperglycemic drug(s) in patients with type 2 Diabetes Mellitus.

In Example 2, non-inferiority of U300 versus Lantus was demonstrated with the least square mean difference in HbA1c versus Lantus of −0.01% (95% CI [−0.139; 0.119]) (Table 26). The least square mean change in pre-injection SMPG was similar in the U300 (−0.56 mmol/L) and Lantus groups (−0.51 mmol/L) (Table 28).

Example 2 confirmed that by treatment with an insulin glargine U300 formulation, the risk of a nocturnal hypoglycemic event can be significantly reduced compared with the treatment with Lantus® U100. In a different patient group, namely type 2 Diabetes Mellitus patients not adequate controlled with antihyperglycemic drug(s) alone, it was surprisingly found that the incidence of patients with at least one nocturnal severe and/or confirmed hypoglycemia between was lower in the U300 group [87/403 (21.6%)] than in the Lantus group [113/405 (27.9%)] (see Table 27). Superiority of U300 versus Lantus was shown with a relative risk of 0.77 (95% CI [0.61, 0.99]) (p=0.0380).

Example 3 compares adaptable dosing intervals with fixed dosing intervals of once-daily administration of an U300 insulin glargine formulation in combination with mealtime insulin. Example 3 is a substudy of the trial described in example 1. No negative effects were seen on HbA1c (Table 50) and on fasting plasma glucose (Table 51). The overall incidence of hypoglycemia was similar in both regimens regardless of the category of hypoglycemia (Table 53).

Example 6 compares adaptable dosing intervals with fixed dosing intervals of once-daily administration of an U300 insulin glargine formulation in combination with oral antihyperglycemic drugs(s). Example 6 is a substudy of the trial described in example 2. No negative effects were seen on HbA1c (Table 67) and on fasting plasma glucose (Table 68). The overall incidence of hypoglycemia was similar in both regimens regardless of the category of hypoglycemia (Table 70).

An aspect of the present invention relates to an aqueous pharmaceutical formulation for use in the treatment of Type I or Type II Diabetes Mellitus, wherein the treatment reduces the risk of nocturnal hypoglycemia, said formulation comprising 200-1000 U/mL [equimolar to 200-1000 IU human insulin] of insulin glargine, with the proviso that the concentration of said formulation is not 684 U/mL of insulin glargine. The present invention relates to an aqueous pharmaceutical formulation for use in the reduction of the risk of nocturnal hypoglycemia.

The formulation of the present invention can reduce the incidence of nocturnal hypoglycemia when administered to a Diabetes Mellitus patient, as described herein. “Reduction of the incidence of nocturnal hypoglycemia” includes reduction of the number of nocturnal hypoglycemic events, and/or the severity of nocturnal hypoglycemia events. The formulation as described herein is suitable for use in the reduction of the incidence of nocturnal hypoglycemia.

The formulation of the present invention can prevent nocturnal hypoglycemia when administered to a Diabetes Mellitus patient, as described herein. “Prevention of nocturnal hypoglycemia” includes reduction of the number of nocturnal hypoglycemic events and/or the severity of nocturnal hypoglycemia events. The formulation as described herein is suitable for use in the prevention of nocturnal hypoglycemia.

The formulation of the present invention is suitable for use in the reduction of the number of nocturnal hypoglycemic events and/or the severity of nocturnal hypoglycemia events.

In the present invention, hypoglycemia is a condition wherein a diabetes mellitus type 2 patient experiences a plasma glucose concentration of below 70 mg/dL (or below 3.9 mmol/L), below 60 mg/dL (or below 3.3 mmol/L), below 54 mg/dL (or below 3.0 mmol/L), below 50 mg/dL, below 40 mg/dL, or below 36 mg/dL.

In the present invention, “symptomatic hypoglycemia” or “symptomatic hypoglycemic event” is a condition associated with a clinical symptom that results from the hypoglycemia, wherein the plasma glucose concentration can be below 70 mg/dL (or below 3.9 mmol/L), below 60 mg/dL (or below 3.3 mmol/L), below 54 mg/dL (or below 3.0 mmol/L), below 50 mg/dL, or below 40 mg/dL. A clinical symptom can be, for example, sweating, palpitations, hunger, restlessness, anxiety, fatigue, irritability, headache, loss of concentration, somnolence, psychiatric disorders, visual disorders, transient sensory defects, transient motor defects, confusion, convulsions, and coma. In the method of the present invention, one or more clinical symptoms of symptomatic hypoglycemia, as indicated herein, can be selected. Symptomatic hypoglycemia may be associated with prompt recovery after oral carbohydrate administration.

In the present invention, “severe symptomatic hypoglycemia” or “severe symptomatic hypoglycemic event” is a condition with a clinical symptom, as indicated herein, that results from hypoglycemia, wherein the plasma glucose concentration can be below 70 mg/dL (or below 3.9 mmol/L), below 54 mg/dL (or below 3.0 mmol/L) or below 36 mg/dL (or below 2.0 mmol/L). Severe symptomatic hypoglycemia can be associated with acute neurological impairment resulting from the hypoglycemic event. In a severe symptomatic hypoglycemia, the patient may require the assistance of another person to actively administer carbohydrate, glucagon, or other resuscitative actions. These episodes may be associated with sufficient neuroglycopenia to induce seizure, unconsciousness or coma. Plasma glucose measurements may not be available during such an event, but neurological recovery attributable to the restoration of plasma glucose to normal is considered sufficient evidence that the event was induced by a low plasma glucose concentration.

The definition of severe symptomatic hypoglycemia may include all episodes in which neurological impairment is severe enough to prevent self-treatment and which were thus thought to place patients at risk for injury to themselves or others. The acute neurological impairment may be at least one selected from somnolence, psychiatric disorders, visual disorders, transient sensory defects, transient motor defects, confusion, convulsions, and coma. “Requires assistance” means that the patient could not help himself or herself. Assisting a patient out of kindness, when assistance is not required, should not be considered a “requires assistance” incident.

Severe symptomatic hypoglycemia may be associated with prompt recovery after oral carbohydrate, intravenous glucose, or/and glucagon administration.

In the present invention, “documented symptomatic hypoglycemia” or “documented symptomatic hypoglycemic event” is an event during which typical symptoms of hypoglycemia accompanied by a measured plasma glucose concentration of 70 mg/dL 3.9 mmol/L), or less than or equal to 54 mg/dL 3.0 mmol/L). Clinical symptoms that are considered to result from a hypoglycemic episode are, e.g., increased sweating, nervousness, asthenia/weakness, tremor, dizziness, increased appetite, palpitations, headache, sleep disorder, confusion, seizures, unconsciousness, coma.

In the present invention, “asymptomatic hypoglycemia” or “asymptomatic hypoglycemic event” is an event not accompanied by typical symptoms of hypoglycemia but with a measured plasma glucose concentration less than or equal to 70 mg/dL (3.9 mmol/L), or less than or equal to 54 mg/dL (3.0 mmol/L).

In the present invention, “probable symptomatic hypoglycemia” or “probable symptomatic hypoglycemic event” is an event during which symptoms of hypoglycemia are not accompanied by a plasma glucose determination, but was presumably caused by a plasma glucose concentration less than or equal to 70 mg/dL (or less than or equal to 3.9 mmol/L), or less than or equal to 54 mg/dL (or less than or equal to 3.0 mmol/L); symptoms treated with oral carbohydrate without a test of plasma glucose.

In the present invention, “relative hypoglycemia” or “relative hypoglycemic event” is an event during which the person with diabetes reports any of the typical symptoms of hypoglycemia, and interprets the symptoms as indicative of hypoglycemia, but with a measured plasma glucose concentration greater than 70 mg/dL (or greater than 3.9 mmol/L).

In the present invention, “nocturnal hypoglycemia” or “nocturnal hypoglycemic event” is any hypoglycemia of the hypoglycema categories as described above that occurs night-time. “Nocturnal hypoglycemia” can be defined by the clock time. In particular, nocturnal hypoglycemia is a hypoglycemia that occurs between 00:00 and 05:59 a.m. hours. The patient can be awake or can wake up because of the event. The patient can also sleep during the event.

In the present invention, “daytime hypoglycemia” or “daytime hypoglycemic event” is in particular any hypoglycemia of the hypoglycema categories as described above that occurs between 06:00 a.m. and 23:59.

In the present invention, the nocturnal hypoglycemia can be a symptomatic hypoglycemia, a severe symptomatic hypoglycemia, a documented symptomatic hypoglycemia, a probable symptomatic hypoglycemia, a relative symptomatic hypoglycemia, or an asymptomatic hypoglycemia. Preferred is a symptomatic hypoglycemia, more preferably a severe symptomatic hypoglycemia.

“Reducing the risk of hypoglycemia”, as used herein, can include reducing the incidence of hypoglycemia. The incidence of hypoglycemia per patient year can be computed per patient as: 365.25×(number of episodes of hypoglycemia)/(number of days exposed) and summarized by type of event and treatment group. “Reducing the risk of hypoglycemia”, as used herein, can further include prevention of hypoglycemia in a patient, when the formulation described herein is administered to a Diabetes Mellitus patient, as described herein. “Reducing the risk of hypoglycemia”, as used herein, can further include reduction of the number of nocturnal hypoglycemic events, and/or the severity of nocturnal hypoglycemia events.

Example 3 and 6 demonstrate that occasional adaptation of injection intervals of insulin glargine U300 have no negative effects on HbA1c (Tables 50 and 67) and on fasting plasma glucose (Tables 51 and 69). The overall incidence of hypoglycemia was similar in administration by adaptable dosing intervals and in administration by a fixed dosing interval regardless of the category of hypoglycemia (Tables 53 and 70).

An aspect of the present invention relates to an aqueous pharmaceutical formulation to be administered in adaptable time intervals. This aspect relates to an aqueous pharmaceutical formulation for use in the treatment of Type I or Type II Diabetes Mellitus, wherein the formulation is administered once daily to a patient, and wherein the time interval from the previous administration is in the range of 24.5 h to 28 h or in the range of 20 h to 23.5 h on at least two days per week, and wherein the average time interval from the previous administration is about 24 h, said formulation comprising 200-1000 U/mL [equimolar to 200-1000 IU human insulin] of insulin glargine, with the proviso that the concentration of said formulation is not 684 U/mL of insulin glargine.

As used herein, the time interval from the previous administration is the time interval between two consecutive administrations, in particular injections.

It is preferred that the formulation comprises 300 U/ml insulin glargin.

In the treatment regimen, the formulation can be administered in a time range around a fixed time, for example around a fixed time in the evening or in the morning. The average time interval from the previous administration can about 24 h (see Table 46). An interval of “about 24 h” in particular refers to a range of 24 h+/−10 min, a range of 24 h+/−20 min, or range of 24 h+/−30 min. The average time interval can be calculated for example, on weekly basis, on monthly basis, or on the basis of two or three months, or can be calculated on a longer time basis.

Table 47 describes the dosing regimen compliance in the test group and control group patients in Example 3. The % of injections by patients in different dosing interval categories is described. In the control group (fixed dosing interval of 24 h), about 88% of U300 doses were injected in an interval of 23 to 25 h from previous injection. About 12% of doses were injected at an interval of less than 23 h or more than 25 h. Taking into account one injection per day, the patients dosed the U300 formulation at an interval of less than 23 h or more than 25 h at less than one day per week. In the test group (adaptable dosing interval), about 63% of U300 doses were injected in an interval of 23 to 25 h from previous injection. About 37% of doses were injected at an interval of less than 23 h or more than 25 h. Taking into account one injection per day, the patients dosed the U300 formulation at an interval of less than 23 h or more than 25 h at two or three days per week.

The aqueous formulation can be administered with the time interval specified herein on at least two days per week, on at least three days per week, on at least four days per week or on at least five days per week.

More particular, the aqueous formulation is administered with the time interval specified herein on two or three days per week, or on two to three days per week.

“Occasional adaptation” in particular means that the aqueous formulation is administered on two or three days per week with the time interval specified herein.

“Days per week”, as indicated herein, can be calculated for example, on weekly basis, on monthly basis, or on the basis of two or three months, or can be calculated on a longer time basis.

“Adaptable injection intervals” means that the time interval from the previous injection is variable within a predetermined time range. The time interval from the previous administration can be in the range of 24.5 h to 28 h or in the range of 20 h to 23.5 h. In particular, the time interval from the previous administration is in the range of 25 h to 28 h or in the range of 20 h to 23 h.

The time interval from the previous administration can also be in the range of 25 h to 27 h or in the range of 21 h to 23 h.

The time interval from the previous administration can also be in the range of 25 h to 26.5 h or in the range of 21.5 h to 23 h.

EXAMPLE 1: 6-MONTH, MULTICENTER, RANDOMIZED, OPEN-LABEL, PARALLEL-GROUP STUDY COMPARING THE EFFICACY AND SAFETY OF A NEW FORMULATION OF INSULIN GLARGINE AND LANTUS® BOTH PLUS MEALTIME INSULIN IN PATIENTS WITH TYPE 2 DIABETES MELLITUS WITH A 6-MONTH SAFETY EXTENSION PERIOD

Synopsis

Phase of Development:

Phase 3

Objectives:

Primary Objective:

To assess the effects on glycemic control of HOE901-U300 in comparison to Lantus when given as basal insulin in a regimen with mealtime insulin in terms of HbA_(1c) change over a period of 6 months in patients with type 2 diabetes mellitus.

Main Secondary Objectives:

To compare HOE901-U300 and Lantus in terms of occurrence of nocturnal hypoglycemia, change in preinjection plasma glucose, and change in variability of preinjection plasma glucose.

Further Secondary Objectives:

-   -   To compare HOE901-U300 and Lantus in terms of reaching target         HbA_(1c) values and controlled plasma glucose;     -   To compare HOE901-U300 and Lantus in terms of treatment         satisfaction of patients using the Diabetes Treatment         Satisfaction Questionnaire (status) (DTSQs) (not presented in         KRM);     -   To assess the safety and tolerability of HOE901-U300.

Methodology:

The randomization was 1:1 (HOE901-U300 versus Lantus) and was stratified according to HbA_(1c) values at screening (<8.0%; ≥8.0%). The sample size (400 with HOE901-U300 and 400 with Lantus) was chosen to ensure sufficient power for the primary endpoint (change in HbA_(1c) from baseline to endpoint [Month 6]) as well as to allow conclusions on the first main secondary endpoint (occurrence of nocturnal hypoglycemia).

Number of patients: Planned: 800 Randomized: 807 (400 per treatment arm) Treated: 806 Evaluated: efficacy: 804 Safety: 806

Diagnosis and Criteria for Inclusion:

Inclusion criteria: Patients with type 2 diabetes mellitus as defined by WHO; signed written informed consent. Key exclusion criteria: Age<18 years; HbA_(1c)<7.0% or >10% at screening; diabetes other than type 2 diabetes mellitus; less than 1 year on basal plus mealtime insulin and self-monitoring of blood glucose; total daily dose insulin glargine <42 U or equivalent dose of NPH in the last 4 weeks prior to the study (if NPH was used as basal insulin prior to the study).

Study Treatments

Investigational Medicinal Products:

Tested drug: HOE901-U300; Control drug: Lantus

Formulations:

HOE901-U300 (insulin glargine 300 U/mL solution) is a sterile, non-pyrogenic, clear, colorless solution in a glass cartridge that has been assembled in a pen-injector (prefilled ie, disposable pen). Lantus (insulin glargine 100 U/mL solution) is a sterile, non-pyrogenic, clear, colorless solution supplied in the marketed Solostar® (prefilled ie, disposable pen).

Route of Administration:

subcutaneous injection

Dose Regimen:

Once daily injection in the evening. The injection time was fixed at the time of randomization and was to be maintained for the duration of the study.

HOE901-U300 or Lantus will be injected once daily subcutaneously in the evening, ie, anytime immediately prior to the evening meal until bedtime. The injection time will be always at the same time within this time window and will be fixed at randomization at the discretion of the patient/investigator. Patients will continue with their mealtime insulin analogue.

Starting Dose:

Patients on Lantus or NPH once daily prior to the baseline visit: the daily dose (U) of HOE901-U300 or Lantus was equal to the median of the total daily basal insulin doses in the last 3 days prior to the baseline visit.

Patients on NPH More than Once Daily Prior to the Baseline Visit:

the daily dose of for HOE901-U300 or Lantus (U) was to be approximately 20% less than the median of the total daily NPH insulin doses in the last 3 days prior to the baseline visit.

The basal insulin dose was adjusted once weekly to achieve fasting SMPG in the target range of 80 to 100 mg/dL (4.4 to 5.6 mmol/L):

-   -   by +3 U, if the median fasting SMPG of last 3 days was in the         range of >100 mg/dL and <140 mg/dL (>5.6 and <7.8 mmol/L)     -   by +6 U, if the median fasting SMPG of last 3 days was 140 mg/dL         (≥7.8 mmol/L)     -   by −3 U, if the median fasting SMPG of last 3 days was in the         range of ≥60 mg/dL and <80 mg/dL (≥3.3 and <4.4 mmol/L).

Mealtime insulin doses were to be adjusted to optimize glycemic control after basal insulin doses have been optimized. Bolus insulin doses could be reduced as basal insulin doses were increased.

Noninvestigational Medicinal Products:

Patients in both treatment groups were to continue with their mealtime insulin analogue during the study. Patients on concomitant metformin treatment were to continue during the study on a stable dose as received prior to the study, unless safety concerns necessitated a dose reduction or discontinuation of metformin.

Duration of Treatment:

Up to 12 months

Duration of Observation:

up to 54 weeks (up to 2-week screening period+6-month efficacy and safety period+6-month safety extension period+2-day safety follow-up).

The analysis period for efficacy and safety is the main 6-month on-treatment period. Results presented in the present KRM refer to this period.

Criteria for Evaluation:

Efficacy:

Primary Efficacy Endpoint:

change in HbA_(1c) from baseline to endpoint (Month 6).

Main Secondary Endpoints:

incidence of patients (%) with at least one nocturnal hypoglycemia between start of Week 9 and endpoint (month 6), indicated as severe and/or confirmed by plasma glucose ≤70 mg/dL (3.9 mmol/L); change in preinjection SMPG from baseline to endpoint (Month 6) and change in variability of preinjection SMPG from baseline to endpoint (Month 6).

Safety:

Hypoglycemia, occurrence of adverse events particularly treatment-emergent adverse events (TEAEs) and serious adverse events (SAEs), injection site reactions and hypersensitivity reactions. Following information not presented in KRM: physical examination, other safety information including clinical laboratory data, vital signs (including body weight), 12-lead ECG and anti-insulin antibodies.

Statistical Methods:

The primary efficacy endpoint (change in HbA_(1c) from baseline to endpoint [Month 6]) was analyzed using an analysis of covariance (ANCOVA) model with treatment, strata of screening HbA_(1c) (<8.0 and ≥8.0%), and country as fixed effects and using the HbA_(1c) baseline value as a covariate. Differences between HOE901-U300 and Lantus and two-sided 95% confidence intervals were estimated within the framework of ANCOVA.

A stepwise closed testing approach was used for the primary efficacy endpoint to assess non-inferiority and superiority sequentially. Step 1 assessed non inferiority of HOE901-U300 versus Lantus. To assess non-inferiority, the upper bound of the two sided 95% CI for the difference in the mean change in HbA1c from baseline to endpoint between HOE901-U300 and Lantus was compared with a predefined non inferiority margin of 0.4% for HbA1c. Non-inferiority would be demonstrated if the upper bound of the two-sided 95% CI of the difference between HOE901-U300 and Lantus on mITT population is <0.4%. Step 2 assessed superiority of HOE901-U300 versus Lantus only if non inferiority was demonstrated. The superiority of HOE901-U300 over Lantus was demonstrated if the upper bound of the two-sided 95% CI of the difference between HOE901-U300 and Lantus on mITT population was <0.

Only if non-inferiority of HOE901-U300 versus Lantus had been demonstrated for the primary endpoint, would testing for superiority of HOE901-U300 over Lantus on the main secondary endpoints occur within the frame of a hierarchical testing procedure. Safety analyses were descriptive, based on the safety population.

Summary:

Population Characteristics:

A total of 807 patients with type 2 diabetes were randomized to HOE901-U300 (n=404) or to Lantus (n=403); 806 patients were exposed to IMP (safety population). The mITT population (efficacy population) included 804 patients.

Overall, a comparable number of patients in each treatment group discontinued the study prematurely (HOE901-U300: 30/404, 7.4%; Lantus 31/403, 7.7%).

Demographics and baseline characteristics were well-balanced between the treatment groups. The mean age of the study population was 60 years, 246/807 (30.4%) were 65 years. The mean BMI at baseline was 36.6 kg/m². The mean duration of diabetes prior to study start was 15.8 years, the mean duration of prior treatment with basal insulin was 6.6 years and the median total daily insulin dose was 1.1 U/kg body weight. In both treatment groups, mean HbA1c at baseline was 8.14%.

Efficacy Results:

Primary endpoint: The LS mean change in HbA1c from baseline to endpoint (Month 6) was similar in both treatment groups (HOE901-U300: −0.83% (95% CI [−0.946; −0.709]); Lantus: −0.83% (95% CI [−0.944; −0.706]). Non-inferiority of HOE901-U300 versus Lantus was demonstrated with the LS mean difference in HbA1c versus Lantus of −0.00% (95% CI [−0.112; 0.107]) with the upper bound lower than the predefined non-inferiority margin of 0.4%. Superiority of HOE901-U300 versus Lantus was not demonstrated.

1^(st) Main Secondary Endpoint:

The incidence of patients with at least one nocturnal severe and/or confirmed hypoglycemia between start of Week 9 and Month 6 was lower in the HOE901-U300 group [136/404 (33.7%)] than in the Lantus group [180/400 (45.0%)]. Superiority of HOE901-U300 versus Lantus was shown with a relative risk of 0.75 (95% CI [0.63, 0.89]) (p=0.0010).

2^(nd) Main Secondary Endpoint:

The LS mean change in pre-injection SMPG from baseline to endpoint (Month 6) was similar in the HOE901-U300 (−0.90 mmol/L) and Lantus groups (−0.84 mmol/L). The difference between the treatment groups was not statistically significant (LS mean difference −0.06 (95% CI [−0.383, 0.255], p=0.6921).

3^(rd) Main Secondary Endpoint:

As the superiority of HOE901-U300 versus Lantus was not demonstrated for the second main secondary endpoint, no further test was performed for the third main secondary endpoint (decrease in variability of pre-injection SMPG at Month 6, which was similar for both treatment groups).

Other Secondary Efficacy Endpoints (Month 6):

Both the proportion of patients having reached HbA1c<7% and the mean change in FPG were similar between treatment groups. Graphical presentation of the 8-point SMPG profiles of HOE901-U300- and Lantus-treated patients showed a marked decrease in plasma glucose at endpoint (Month 6) compared with baseline. The profiles of the 2 treatment groups are almost superimposable at both baseline and endpoint.

The increase of basal insulin dose in the HOE901-U300 group resulted in a mean daily dose of 103 U at Month 6 compared to Lantus group with a mean daily dose of 94 U (the mean basal insulin dose at baseline was 70 U in both treatment groups). The increase of the daily mealtime insulin dose was comparable between treatment groups with a small increase in the first two weeks. Thereafter, mealtime insulin doses remained stable.

Safety Results:

Overall, hypoglycemia was reported by a consistently lower percentage of patients in the HOE901-U300 group than in the Lantus group. This difference was even more pronounced during the first 2 months of study treatment as well as for events of nocturnal hypoglycemia. During the main 6-month on-treatment period severe hypoglycemia was reported in 21/404 (5.2%) of HOE901-U300 treated patients and 23/402 (5.7%) of Lantus treated patients.

The percentages of patients with any TEAEs (HOE901-U300, 222/404 [55.0%]; Lantus: 215/402 [53.5%]) or with serious TEAEs (HOE901-U300, 25 [6.2%]; Lantus, 21 [5.2%]) were similar between both groups. A similar proportion of patients experienced serious cardiac TEAEs (SOC—cardiac disorders) in both treatment groups (HOE901-U300: n=5, 1.2%; Lantus: n=7; 1.7%).

Six patients died during the study, 3 (0.7%) in each treatment group. Of these, 4 patients died during the first 6 months, 2 (0.5%) in each treatment group. The events with fatal outcome in the three patients in the HOE901-U300 group included the following conditions: infected thrombosis and embolism in the heart, bronchogenic carcinoma with metastasis and—for the third patient—pulmonary emboli. The leading cause of the fatal events in the three patients in the Lantus group included: chronic depression and intoxication with medication, one patient had multitude of conditions including worsening of chronic heart failure (NYHA IV), chronic kidney failure stage 4 with acute decompensation, decompensated diabetes and diabetic nephropathy contributing to the fatal outcome and the last patient suffered acute cardiopulmonary arrest of unknown etiology. None of the deaths were considered related to study drug. A similar number of patients in both treatment groups experienced TEAEs leading to permanent treatment discontinuation (HOE901-U300: n=6, 1.5%; Lantus: n=7, 1.7%).

Hypersensitivity reactions during the main 6-month on-treatment period were reported at a similar rate in both treatment groups (HOE901-U300: n=3, 0.7%; Lantus: n=2, 0.5%).

Overall injection site reactions during the main 6-month on-treatment period showed similar rate in both treatment groups (HOE901-U300: n=9, 2.2%; Lantus: n=6, 1.5%).

Conclusions:

In this study in 807 patients with T2DM on basal insulin in combination with mealtime insulin, the baseline characteristics and demographic characteristics were well balanced across treatment groups. Non-inferiority of HOE901-U300 versus Lantus was shown for the primary efficacy endpoint (change in HbA1c from baseline to endpoint [Month 6]). The incidence of patients (%) reporting nocturnal hypoglycemia (severe and/or confirmed by SMPG ≤70 mg/dL [3.9 mmol/L]) between start of Week 9 and Month 6 was significantly lower in the HOE901-U300 group than in the Lantus group (33.7% and 45% respectively, RR of 0.75, p-value 0.0010; 1^(st) main secondary efficacy endpoint). Comparable results between the treatment groups were found for other secondary endpoints such as pre-injection plasma glucose, variability of pre-injection plasma glucose, number of patients reaching target HbA1c, mean change of FPG and 8-point profiles of plasma glucose.

Overall incidence of hypoglycemia (% of patients with at least one event) during the main 6-month on-treatment period was lower in the HOE901-U300 group than in the Lantus group regardless of the category of hypoglycemia.

HOE901-U300 was well tolerated during the main 6-month on-treatment period of the study and no specific safety concerns were observed.

Summary of the efficacy and safety results of the twelve month EDITION 1 extension study

-   -   HbA1c: during the safety extension period (from the main study         endpoint [Month 6] to the End of Treatment [Month 12]) HbA1c         remained stable and was comparable in both treatment groups     -   hypoglycemia: overall, similarly as during the main 6-month         treatment period, during the whole study on-treatment period         hypoglycemia occurred in a similar or lower percentage of         patients in the HOE901-U300 group than in the Lantus group     -   safety: HOE901-U300 was well tolerated during the study and no         specific safety concerns were observed; during the whole         treatment period, the percentages of patients with any TEAEs         were similar in both groups (289/404 [71.5%] in the HOE901-U300         and 278/402 [69.2%] in the Lantus treatment group), with no         specific SOC contributing. Serious TEAEs were reported by a         similar number of patients: (53 [13.1%]) in the HOE901-U300 and         62 [15.4%] in the Lantus treatment group). Two (0.5%) patients         in the HOE901-U300 and 4 (1.0%) patient in the Lantus treatment         group had TEAE leading to death during the whole study         on-treatment period     -   body weight: in both treatment groups, during the whole study         on-treatment period there was small increase in body weight         (1.17 kg for HOE901-U300 and 1.40 kg for Lantus).

At V1 (week-2), the investigator or a member of the investigational staff will provide patients with a blood glucometer and the corresponding supplies (needles, control solutions, test strips etc.) and with diaries in order to perform self-measurement of plasma glucose and its recording. Patients will be shown how to accurately measure plasma glucose values with the blood glucometer. The investigator or a member of the investigational staff will explain the need to measure glucose at the times requested for profiles and to correctly record the values in the patient diaries. Training is repeated as often as necessary at the study visits and the investigational staff reviews the patient's diary at each visit. Blood glucose values will be measured by the patient using the sponsor-provided blood glucose meter. Patients will document their SMPG data in the diary.

The patients will be instructed to bring the blood glucometers provided by the sponsor with them to each office visit. The blood glucometers should be calibrated according to instructions given in the package leaflet and the investigational site should also check regularly the glucometers using the provided control solutions for data validity.

Starting with V1 (screening visit), the diary includes sections for recording by patients of

-   -   Study treatment and mealtime insulin: time and dose of         HOE901-U300 or Lantus injections (Lantus or NPH injections         during screening period) and mealtime/bolus insulin analogue         injections;     -   SMPG: time and value of SMPG;         -   1. Fasting SMPG in the morning (prebreakfast)         -   2. SMPG within 30 minutes prior to injection of basal             insulin during 7 days before each visit         -   3. 4-point profile and 8-point profile SMPG         -   4. SMPG related to hypoglycemic events         -   5. Any other SMPG (whatever the reason of measurement)

SMPG measurements are scheduled as follows:

-   -   Fasting plasma glucose (SMPG): The fasting (prebreakfast) SMPG         will be measured daily throughout the study. During the week         before visit 3 (Day 1, Baseline) compliance to the fasting SMPG         measurement schedule will be used to assess eligibility for         entry in the randomized treatment period. During the study, when         uptitration has been completed and fasting (prebreakfast) SMPG         is stable in the target range, at least of 3 measurements per         week should be performed.     -   Plasma glucose within 30 minutes prior to injection of study         drug (preinjection SMPG): Preinjection SMPG will be done within         30 min prior to the injection of the IMP (HOE901-U300 or Lantus)         on at least 7 days before baseline and before each on site visit         throughout the study. At days when 4-point or 8-point profiles         are done: if time of preinjection SMPG is the same as a time         point of the 4-point or 8-point profile, the SMPG value has to         be assigned by the patient in the diary to both (eg,         preinjection PG; bedtime).     -   4-point SMPG profiles (prebreakfast, prelunch, predinner,         bedtime): During the week before baseline visit and during the         first 12 weeks of treatment with IMP, patients will perform         4-point SMPG profiles at least on 3 days per week. Once the         titration goal is reached, the number of 4-point SMPG profiles         can be reduced according to the investigator's judgment but         4-point SMPG profiles at least on 3 days in the week before each         visit are mandatory. It is, however, recommended to perform         4-point SMPG profiles daily throughout the study for optimal         adjustment of the insulin regimen;     -   8-point blood glucose profiles (starting with a measurement at         03:00 am at night; before and 2 hours after breakfast; before         and 2 hours after lunch; before and 2 hours after dinner; at         bedtime): Patients will perform 8-point SMPG profiles at least         one day in the 5 days before each on-site visit. It is, however,         recommended to perform 8-point SMPG profiles at least once         weekly up to week 8, and once every second week thereafter.         Special attention should be paid that the 3.00 a.m. SMPG value         is recorded.     -   SMPG during episodes of symptomatic hypoglycemia: Whenever the         patients feel hypoglycemic symptoms, plasma glucose should be         measured by the patient (or others, if applicable), if possible.         Patients should be instructed to measure plasma glucose levels         prior to the administration of glucose or carbohydrate intake         whenever symptomatic hypoglycemia is suspected, unless safety         considerations necessitate immediate glucose/carbohydrate rescue         prior to confirmation.

The following SMPG values have to be copied into the eCRF:

During the week prior to baseline visit and during the first 12 weeks until Visit 8 (week 12):

-   -   Fasting (prebreakfast) SMPG: daily     -   Preinjection SMPG (within 30 minutes prior to injection of the         basal insulin): at 7 days prior to each on-site visit     -   4-point profile SMPG: at 3 different days in each week until         visit 8 (week 12)     -   8-point profile SMPG: 1 profile within 5 days before each         on-site visit     -   SMPG related to hypoglycemic event: whenever documented

Note: following phone call visits the following data at the minimum will be entered into the e-CRF: fasting (prebreakfast) SMPG over last 3 days, SMPG related to hypoglycemic event: whenever documented. The remaining SMPG data of the week prior to the phone call visits will be entered into the e-CRF at a subsequent on-site visit. After Visit 8 (week 12):

-   -   Fasting (prebreakfast) SMPG: during 7 days before each on-site         visit     -   Preinjection SMPG (within 30 minutes prior to injection of the         basal insulin): at 7 days prior to each on-site visit     -   4-point profile SMPG: at 3 different days within 7 days before         each on-site visit     -   8-point profile SMPG: at one day within 5 days before each         on-site visit     -   SMPG related to hypoglycemic event: whenever documented

All glucose values will be used by the investigator to monitor glycemia.

Hypoglycemia events are categorized as follows (American Diabetes Association Workgroup on Hypoglycemia. Defining and Reporting Hypoglycemia in Diabetes. Diabetes Care 2005; 28:1245-49):

Severe Hypoglycemia

Severe hypoglycemia is an event requiring assistance of another person to actively administer carbohydrate, glucagon, or other resuscitative actions.

These episodes may be associated with sufficient neuroglycopenia to induce seizure, unconsciousness or coma. Plasma glucose measurements may not be available during such an event, but neurological recovery attributable to the restoration of plasma glucose to normal is considered sufficient evidence that the event was induced by a low plasma glucose concentration.

The definition of severe symptomatic hypoglycemia includes all episodes in which neurological impairment was severe enough to prevent self-treatment and which were thus thought to place patients at risk for injury to themselves or others.

Note that “requires assistance” means that the patient could not help himself or herself. Assisting a patient out of kindness, when assistance is not required, should not be considered a “requires assistance” incident.

Severe symptomatic hypoglycemia will be qualified as an SAE only if it fulfills SAE criteria. All events of seizure, unconsciousness or coma must be reported as SAEs.

Documented Symptomatic Hypoglycemia

Documented symptomatic hypoglycemia is an event during which typical symptoms of hypoglycemia accompanied by a measured plasma glucose concentration of ≤70 mg/dL (3.9 mmol/L) (American Diabetes Association Workgroup on Hypoglycemia. Defining and Reporting Hypoglycemia in Diabetes. Diabetes Care 2005; 28:1245-49).

Clinical symptoms that are considered to result from a hypoglycemic episode are, eg, increased sweating, nervousness, asthenia/weakness, tremor, dizziness, increased appetite, palpitations, headache, sleep disorder, confusion, seizures, unconsciousness, coma.

Asymptomatic Hypoglycemia

Asymptomatic hypoglycemia is an event not accompanied by typical symptoms of hypoglycemia but with a measured plasma glucose concentration less than or equal to 70 mg/dL (3.9 mmol/L);

Probable Symptomatic Hypoglycemia

Probable symptomatic hypoglycemia is an event during which symptoms of hypoglycemia are not accompanied by a plasma glucose determination, but was presumably caused by a plasma glucose concentration less than or equal to 70 mg/dL (3.9 mmol/L); symptoms treated with oral carbohydrate without a test of plasma glucose.

Relative Hypoglycemia

Relative hypoglycemia is an event during which the person with diabetes reports any of the typical symptoms of hypoglycemia, and interprets the symptoms as indicative of hypoglycemia, but with a measured plasma glucose concentration greater than 70 mg/dL (3.9 mmol/L).

Nocturnal Hypoglycemia

Nocturnal hypoglycemia is any hypoglycemia of the above categories that occurs between 00:00 and 05:59 hours. Note: Relative nocturnal hypoglycemia will not be included in the analysis of the main secondary endpoint (patients with at least one nocturnal hypoglycemia).

In addition of the threshold of less than or equal to 70 mg/dL (3.9 mmol/L), hypoglycemia episodes with a plasma glucose of <54 mg/dL (3.0 mmol/L) will be analyzed separately (Guideline on clinical investigation of medicinal products in the treatment of diabetes mellitus. Draft. EMA, 20 Jan. 2010).

The classification of hypoglycemia will be done on basis of the clock time: Hypoglycemia episodes will be analyzed by their diurnal distribution (0:00-24:00) and in addition by time of the day:

-   -   nocturnal hypoglycemia defined by time of the day: any         hypoglycemia of the above categories that occurs between 00:00         and 05:59 a.m. hours, regardless whether patient was awake or         woke up because of the event);     -   daytime hypoglycemia: any hypoglycemia of the above categories         that occurs between 6:00 a.m. and 23:59.

Patients will be instructed to measure finger stick plasma glucose levels prior to the administration of carbohydrates whenever symptomatic hypoglycemia is suspected, unless safety considerations necessitate immediate glucose rescue prior to confirmation, and then a glucose measurement should be performed as soon as safe, with appropriate diary documentation.

Details on hypoglycemia episodes will be captured in the patient diaries, and patients will contact the sites as soon as possible following severe events to review the details and decide on any necessary measures to be taken.

All hypoglycemia episodes will be documented on the “hypoglycemia specific form” in the e-CRF. This includes all symptomatic hypoglycemia events and asymptomatic hypoglycemia. Hypoglycemia events fulfilling the criteria of a SAE will be documented on the SAE form in the e-CRF.

Incidences of hypoglycemia per patient year will be computed per patient as: 365.25×(number of episodes of hypoglycemia)/(number of days exposed) and summarized by type of event and treatment group.

EXAMPLE 2: 6-MONTH, MULTICENTER, RANDOMIZED, OPEN-LABEL, PARALLEL-GROUP STUDY COMPARING THE EFFICACY AND SAFETY OF A NEW FORMULATION OF INSULIN GLARGINE AND LANTUS® BOTH IN COMBINATION WITH ORAL ANTIHYPERGLYCEMIC DRUG(S) IN PATIENTS WITH TYPE 2 DIABETES MELLITUS WITH A 6-MONTH SAFETY EXTENSION PERIOD)

Synopsis

Study Center(s):

Multicenter

Phase of Development:

3

Objectives:

Primary Objective: To assess the effects on glycemic control of HOE901-U300 in comparison to Lantus when given as basal insulin in a regimen with oral antihyperglycemic drug(s) in terms of HbA1c change over a period of 6 months in patients with type 2 diabetes mellitus.

Main secondary Objectives: To compare HOE901-U300 and Lantus in terms of occurrence of nocturnal hypoglycemia, change in preinjection plasma glucose, and change in variability of preinjection plasma glucose.

Further secondary objectives:

-   -   To compare HOE901-U300 and Lantus in terms of reaching target         HbA_(1c) values and controlled plasma glucose;     -   To compare HOE901-U300 and Lantus in terms of treatment         satisfaction of patients using the Diabetes Treatment         Satisfaction Questionnaire (status) (DTSQs) (not presented in         KRM);     -   To assess the safety and tolerability of HOE901-U300.

Methodology:

The randomization was 1:1 (HOE901-U300 versus Lantus) and was stratified according to HbA_(1c) values at screening (<8.0%; 8.0%). The sample size (400 with HOE901-U300 and 400 with Lantus) was chosen to ensure sufficient power for the primary endpoint (change in HbA_(1c) from baseline to endpoint [Month 6]) as well as to allow conclusions on the first main secondary endpoint (occurrence of nocturnal hypoglycemia).

Number of Patients:

Planned: 800 (400 per Randomized: 811 Treated: 809 treatment arm) Evaluated: Efficacy: 808 Safety: 809

Diagnosis and Criteria for Inclusion:

Inclusion criteria: Patients with type 2 diabetes mellitus as defined by WHO diagnosed for at least 1 year at the time of the screening visit; signed written informed consent. Key exclusion criteria: Age <18 years; HbA_(1c)<7.0% or >10% at screening; diabetes other than type 2 diabetes mellitus; Less than 6 months on basal insulin treatment together with oral antihyperglycemic drugs and self-monitoring of blood glucose; total daily dose insulin glargine <42 U or equivalent dose of NPH in the last 4 weeks prior to the study (if NPH was used as basal insulin prior to the study).

Study Treatments

Investigational Medicinal Products:

Tested drug: HOE901-U300; Control drug: Lantus

Formulations:

HOE901-U300 (insulin glargine 300 U/mL solution) is a sterile, non-pyrogenic, clear, colorless solution in a glass cartridge that has been assembled in a pen-injector (prefilled ie, disposable pen). Lantus (insulin glargine 100 U/mL solution) is a sterile, non-pyrogenic, clear, colorless solution supplied in the marketed Solostar® (prefilled ie, disposable pen).

Route of Administration:

subcutaneous injection

Dose Regimen:

Once daily injection in the evening. The injection time was fixed at the time of randomization and was to be maintained for the duration of the study.

Starting Dose:

Patients on Lantus or NPH once daily prior to the baseline visit: the daily dose (U) of HOE901-U300 or Lantus was equal to the median of the total daily basal insulin doses in the last 3 days prior to the baseline visit.

Patients on NPH more than once daily prior to the baseline visit: the daily dose of for HOE901-U300 or Lantus (U) was to be approximately 20% less than the median of the total daily NPH insulin doses in the last 3 days prior to the baseline visit.

The basal insulin dose was adjusted once weekly to achieve fasting SMPG in the target range of 80 to 100 mg/dL (4.4 to 5.6 mmol/L):

-   -   by +3 U, if the median fasting SMPG of last 3 days was in the         range of >100 mg/dL and <140 mg/dL (>5.6 and <7.8 mmol/L)     -   by +6 U, if the median fasting SMPG of last 3 days was 140 mg/dL         7.8 mmol/L)     -   by −3 U, if the median fasting SMPG of last 3 days was in the         range of 60 mg/dL and <80 mg/dL 3.3 and <4.4 mmol/L).

Rescue Treatment:

If the basal insulin adjustment failed to decrease FPG/HbA1c under the threshold values of 11.1 mmol/L (200 mg/dL) for FPG and 8% for HbA1c at week 12 or later and no apparent reason for insufficient control was identified, intensification of the treatment was to be considered. The choice of the anti-diabetic treatment to be added to the basal insulin and oral antihyperglycemic background therapy was based on Investigator's decision and local labeling documents.

Noninvestigational Medicinal Products:

Patients in both treatment groups were to continue with their oral antihyperglycemic background therapy at a stable dose during the study, except sulfonylurea which were prohibited within 2 months before the screening visit and during the study. Rescue therapy was also considered as non investigational medicinal product.

Duration of Treatment:

Up to 12 months

Duration of Observation:

up to 58 weeks (up to 2-week screening period+6-month efficacy and safety period+6-month safety extension period+a 4-week post-treatment follow up period)

The analysis period for efficacy and safety is the main 6-month on-treatment period. Results presented in the present KRM refer to this period.

For all patients requiring rescue therapy during the 6-month treatment period, the last post-baseline efficacy measurement before the start of rescue therapy was used as the efficacy endpoint. These patients were excluded from efficacy analyses after initiation of rescue treatment. For safety endpoints; the analysis period is the main 6-month on-treatment period regardless of the use of rescue therapy.

Criteria for Evaluation:

Efficacy:

Primary Efficacy Endpoint:

change in HbA_(1c) from baseline to endpoint (Month 6).

Main Secondary Endpoints:

incidence of patients (%) with at least one nocturnal hypoglycemia between start of Week 9 and endpoint (month 6), indicated as severe and/or confirmed by plasma glucose ≤70 mg/dL (3.9 mmol/L); change in preinjection SMPG from baseline to endpoint (Month 6) and change in variability of preinjection SMPG from baseline to endpoint (Month 6).

Safety:

Hypoglycemia, occurrence of adverse events particularly treatment-emergent adverse events (TEAEs) and serious adverse events (SAEs), TEAEs leading to withdrawal and TEAEs leading to death, injection site reactions and hypersensitivity reactions. Following information not presented in this KRM: physical examination, other safety information including clinical laboratory data, vital signs, 12-lead ECG and anti-insulin antibodies.

Following information not presented in this KRM: physical examination, other safety information including clinical laboratory data, vital signs, 12-lead ECG and anti-insulin antibodies.

Statistical Methods:

The primary efficacy endpoint (change in HbA_(1c) from baseline to endpoint [Month 6]) was analyzed using an analysis of covariance (ANCOVA) model with treatment, strata of screening HbA_(1c) (<8.0 and ≥8.0%), and country as fixed effects and using the HbA_(1c) baseline value as a covariate. Differences between HOE901-U300 and Lantus and two-sided 95% confidence intervals were estimated within the framework of ANCOVA.

A stepwise closed testing approach was used for the primary efficacy endpoint to assess non-inferiority and superiority sequentially. Step 1 assessed non inferiority of HOE901-U300 versus Lantus. To assess non-inferiority, the upper bound of the two sided 95% CI for the difference in the mean change in HbA1c from baseline to endpoint between HOE901-U300 and Lantus was compared with a predefined non inferiority margin of 0.4% for HbA1c. Non-inferiority would be demonstrated if the upper bound of the two-sided 95% CI of the difference between HOE901-U300 and Lantus on mITT population is <0.4%. Step 2 assessed superiority of HOE901-U300 versus Lantus only if non inferiority was demonstrated. The superiority of HOE901-U300 over Lantus was demonstrated if the upper bound of the two-sided 95% CI of the difference between HOE901-U300 and Lantus on mITT population was <0.

Only if non-inferiority of HOE901-U300 versus Lantus had been demonstrated for the primary endpoint, would testing for superiority of HOE901-U300 over Lantus on the main secondary endpoints occur within the frame of a hierarchical testing procedure. Safety analyses were descriptive, based on the safety population.

Summary:

Population Characteristics:

A total of 811 patients with type 2 diabetes mellitus were randomized to HOE901-U300 (n=404) or to Lantus (n=407); 809 patients were exposed to IMP (safety population). The mITT population (efficacy population) included 808 patients.

Overall, a comparable number of patients in each treatment group discontinued the study treatment prematurely (HOE901-U300: 36/404, 8.9%; Lantus 38/407, 9.3%). A total of 344 (85.1%) patients in the HOE901-U300 arm and 349 (85.7%) in the Lantus arm completed the main 6-month treatment period (patients who received rescue medication were excluded from the completers population).

Demographics and baseline characteristics were well-balanced between the treatment groups. The mean age of the study population was 58.2 years, 190/811 (23.4%) were 65 years. The mean BMI at baseline was 34.8 kg/m². There were slightly more patients with a BMI above 40 kg/m² in the HOE901-U300 group (21.5%) than in the Lantus group (16.7%). The mean duration of diabetes prior to study start was 12.6 years; the mean duration of prior treatment with basal insulin was 3.8 years. The majority of patients took insulin glargine (78.8% vs. NPH 21.2%) on the 7 days before start of study treatment; more patients from the Lantus group were on insulin glargine (82.8%) compared to the HOE901-U300 group (74.9%). The median daily basal insulin dose at baseline was 0.614 U/kg body weight.

Mean HbA1c at baseline was similar in both treatment groups (HOE901-U300: 8.28% and Lantus: 8.22%; for evaluable patients, i.e. who had a baseline and at least one post-baseline HbA1c assessment).

Efficacy Results:

Primary Endpoint:

The LS mean change in HbA1c from baseline to endpoint (Month 6) was similar in both treatment groups (HOE901-U300: −0.57% (95% CI [−0.756; −0.387]); Lantus: −0.56% (95% CI [−0.744; −0.379]). Non-inferiority of HOE901-U300 versus Lantus was demonstrated with the LS mean difference in HbA1c versus Lantus of −0.01% (95% CI [−0.139; 0.119]) with the upper bound lower than the predefined non-inferiority margin of 0.4%. Non-inferiority was also the case with the non-inferiority margin of 0.3%. Superiority of HOE901-U300 versus Lantus was not demonstrated.

1st Main Secondary Endpoint:

The incidence of patients with at least one nocturnal severe and/or confirmed hypoglycemia between start of Week 9 and Month 6 was lower in the HOE901-U300 group [87/403 (21.6%)] than in the Lantus group [113/405 (27.9%)]. Superiority of HOE901-U300 versus Lantus was shown with a relative risk of 0.77 (95% CI [0.61, 0.99]) (p=0.0380).

2nd Main Secondary Endpoint:

The LS mean change in pre-injection SMPG from baseline to endpoint (Month 6) was similar in the HOE901-U300 (−0.56 mmol/L) and Lantus groups (−0.51 mmol/L). The difference between the treatment groups was not statistically significant (LS mean difference −0.04 (95% CI [−0.438, 0.350], p=0.8279).

3rd Main Secondary Endpoint:

As the superiority of HOE901-U300 versus Lantus was not demonstrated for the second main secondary endpoint, no further test was performed for the third main secondary endpoint (decrease in variability of pre-injection SMPG at Month 6, which was numerically larger in the HOE901-U300 group (−2.34) compared to the Lantus group (−0.53).

Other Secondary Efficacy Endpoints (Month 6):

The proportion of patients having reached HbA1c<7% was similar between treatment groups (30.6% in the HOE901-U300; 30.4% in the Lantus). For the mean change in FPG, a similar decrease was shown for the two treatment groups. Graphical presentation of the 8-point SMPG profiles showed in both treatment groups a comparable, marked decrease in plasma glucose at endpoint (Month 6) compared with baseline.

At month 6, the mean daily insulin dose in the HOE901-U300 group was 91 U (0.92 U/kg) and 82 U (0.84 U/kg) in the Lantus group.

A similar number of patients in both treatment groups received a rescue therapy during the main 6-month treatment period (5.7% for HOE901-U300, 4.9% for Lantus.

Safety Results:

Overall, hypoglycemia was reported by a consistently lower percentage of patients in the HOE901-U300 group than in the Lantus group. This difference was even more pronounced during the first 2 months of study treatment as well as for events of nocturnal hypoglycemia. During the main 6-month on-treatment period severe hypoglycemia was reported in 4/403 (1%) of HOE901-U300 treated patients and 6/406 (1.5%) of Lantus treated patients.

The percentages of patients with any TEAEs (HOE901-U300, 236/403 [58.6%]; Lantus: 206/406 [50.7%]) was higher for the patients in the HOE901-U300 treatment group than in the Lantus group, with no specific SOC contributing. Serious TEAEs were reported by a similar number of patients in both treatment groups (HOE901-U300, 15 [3.7%]; Lantus, 15 [3.7%]).

Two (0.5%) patients in the HOE901-U300 and 1 (0.2%) patient in the Lantus treatment group died during the 6-months on-treatment period.

The events with fatal outcome in the two patients in the HOE901-U300 group included myocardial infarction and sudden cardiac death due to advanced coronary artery disease. Both patients suffered from pre-existing significant cardiovascular pathology and had multiple risk factors contributing to the fatal outcome. The patient in the Lantus group experienced exacerbation of chronic pyelonephritis with fatal outcome. None of the deaths occurred during the 6 months treatment period were considered related to study drug.

A similar number of patients in both treatment groups experienced TEAEs leading to permanent treatment discontinuation (HOE901-U300: n=6, 1.5%; Lantus: n=4, 1.0%).

Hypersensitivity reactions during the main 6-month on-treatment period were reported at a similar rate in both treatment groups (HOE901-U300: n=13, 3.2%; Lantus: n=16, 3.9%).

Overall injection site reactions during the main 6-month on-treatment period showed higher rate of reporting in the Lantus treatment group than in the HOE901-U300 group (Lantus: n=12, 3.0%; HOE901-U300: n=4, 1.0%).

In both treatment groups, there was no apparent change in body weight (0.08 kg for HOE901-U300 and 0.66 kg for Lantus).

Conclusions:

In this study in 811 patients with T2DM on basal insulin in combination with oral antidiabetic drug(s), the baseline characteristics and demographic characteristics were well balanced across treatment groups. Non-inferiority of HOE901-U300 versus Lantus was shown for the primary efficacy endpoint (change in HbA1c from baseline to endpoint [Month 6]). The incidence of patients (%) reporting nocturnal hypoglycemia (severe and/or confirmed by SMPG ≤70 mg/dL [3.9 mmol/L]) between start of Week 9 and Month 6 was significantly lower in the HOE901-U300 group than in the Lantus group (21.6% and 27.9% respectively, RR of 0.77, p-value 0.0380; 1st main secondary efficacy endpoint). Comparable results between the treatment groups were found for the other secondary endpoints of pre-injection plasma glucose, variability of pre-injection plasma glucose, number of patients reaching target HbA1c and mean change of FPG, change of 8-point SMPG profile and variability of 24-hour average plasma glucose.

Overall incidence of hypoglycemia (% of patients with at least one event) during the main 6-month on-treatment period was consistently lower in the HOE901-U300 group than in the Lantus group regardless of the category of hypoglycemia. This difference in favor of HOE901-U300 was even more pronounced for nocturnal hypoglycemia of all categories.

HOE901-U300 was well tolerated during the main 6-month on-treatment period of the study and no specific safety concerns were observed.

Summary of the efficacy and safety results of the twelve month EDITION 2 extension study

-   -   HbA1c: during the safety extension period (from the main study         endpoint [Month 6] to the End of Treatment [Month 12]) HbA1c         remained stable and was comparable in both treatment groups     -   rescue: during the whole treatment period, the percentages of         patients requiring a rescue therapy was similar in both         treatment groups (8.2% for HOE901-U300, 10.1% for Lantus).         During the 6-month safety extension period rescue therapy was         started in lower percentage of patients in the HOE901-U300         treatment group than in the Lantus group (2.5% for HOE901-U300,         5.4% for Lantus)     -   hypoglycemia: overall, similarly as during the main 6-month         treatment period, during the whole study on-treatment period         hypoglycemia occurred in a lower percentage of patients in the         HOE901-U300 group than in the Lantus, regardless of category of         hypoglycemia     -   safety: HOE901-U300 was well tolerated during the study and no         specific safety concerns were observed; during the whole         treatment period, the percentages of patients with any TEAEs was         higher for the patients in the HOE901-U300 treatment group than         in the Lantus group (278/403 [69.0%] and 244/406 [60.1%],         respectively), with no specific SOC contributing. Serious TEAEs         were reported by a similar number of patients (30 [7.4%]) in         both treatment groups. Four (1.0%) patients in the HOE901-U300         and 2 (0.5%) patient in the Lantus treatment group had TEAE         leading to death during the whole study on-treatment period     -   body weight: in both treatment groups, during the whole study         on-treatment period there was small increase in body weight         (0.41 kg for HOE901-U300 and 1.15 kg for Lantus).

1 Synopsis

Phase of development:

3

Objectives:

Primary Objective: To compare the efficacy of HOE901-U300 injected once daily every 24 hours and HOE901-U300 injected once daily at intervals of 24±3 hours in terms of change of HbA1c from month 6 of the main study (=baseline of sub-study) to month 9 of the main study (=endpoint of sub-study) in patients with type 2 diabetes mellitus.

Main secondary Objectives: To compare the safety of the two injection regimens for HOE901-U300 in terms of occurrence of hypoglycemia.

Methodology:

Patients randomized on HOE901-U300 and having received HOE901-U300 in the 6-month main study period are randomized 1:1 to administer HOE901-U300 once daily either every 24 hours (fixed dosing intervals) or every 24±3 hours (adaptable dosing intervals).

Patients on HOE901-U300 completing the 6 months main study period (see Example 1) and meeting the eligibility criteria for the sub-study were eligible for the sub-study. No specific sample size was requested for the primary analysis that is descriptive.

Number of patients: Planned: up to 300 (150 pre-treatment arm) Randomized: 110 Treated: 110 Evaluated: Efficacy: 109 Safety: 110

Diagnosis and Criteria for Inclusion:

Inclusion criteria: Completion of the 6-month study period in main study described in Example 1 (Visit 10), Randomized and treated with HOE901-U300 during the 6-month treatment period (Baseline—month 6), Signed written informed consent for sub-study obtained.

Key Exclusion Criteria:

Patient not willing to use the adaptable injection intervals of 24±3 hours on at least two days per week; In the investigator's opinion, not able to comply with an adaptable dosing schedule; Health condition which precludes further participation of the patient in the study.

Study Treatments

Investigational Medicinal Product:

Tested drug: HOE901-U300

Formulation: HOE901-U300 (insulin glargine 300 U/mL solution) is a sterile, non-pyrogenic, clear, colorless solution in a glass cartridge assembled in a pen-injector (prefilled, disposable pen).

Route of administration: subcutaneous injection

Tested Regimen:

Adaptable dosing intervals: HOE901-U300 administered once daily every 24±3 hours.

The injection time may have been adapted according to individual needs by up to 3 hours earlier or later than the daily injection time in the evening fixed at the start of the main study. The maximum intervals, ie, 3 hours earlier or 3 hours later than the fixed daily injection time was to be used on at least 2 days of the week at the patients' choice. The injection time fixed at start of the main study was to be maintained as reference time for the variation.

Control Regimen:

Fixed dosing intervals: HOE901-U300, once daily injection every 24 hours.

Patients continued to inject HOE901-U300 once daily every 24 hours at the injection time fixed at start of the main study.

Dose:

The dose of HOE901-U300 was to be titrated as needed to achieve or maintain fasting plasma glucose in the target range of 80 to 100 mg/dL (4.4 mmol/L to 5.6 mmol/L) without hypoglycemia. Changes in the insulin dose were based on fasting self-monitored capillary plasma glucose (SMPG) measurements.

Non-Investigational Medicinal Products

Patients in both treatment groups were to continue with their mealtime insulin analogue during the sub-study.

Patients on concomitant metformin treatment were to continue during the sub-study on a stable dose, unless safety concerns necessitated a dose reduction or discontinuation of metformin

Duration of Treatment:

The sub-study consisted of a 3 month comparative efficacy and safety treatment period starting at completion of the 6-month main study period and ending at completion of Month 9 of the main study.

After completion, patients on the adaptable dosing arm may have continued this regimen up to the end of the main study (Month 12). Patients injecting HOE901-U300 every 24 hours continued with their treatment regimen up to the end of the study.

Duration of Observation:

The analysis period for efficacy and safety is the 3-month study period starting at Month 6 of the main study and ending at Month 9 of the main study. Results presented in the present KRM refer to this period.

Criteria for Evaluation:

Efficacy:

Primary Efficacy Endpoint:

change in HbA_(1c) from baseline (Month 6) to endpoint (Month 9).

Secondary Endpoints:

FPG (central laboratory) change from baseline (Month 6) to endpoint (Month 9), daily dose of basal insulin and mealtime insulin.

Safety:

Hypoglycemia, occurrence of adverse events particularly treatment-emergent adverse events (TEAEs) and serious adverse events (SAEs), injection site reactions and hypersensitivity reactions. Following information not presented in KRM: other safety information including vital signs and overdose.

Statistical Methods: For this 3-month sub-study, Baseline is defined as Month 6 of the main study period; the Endpoint is month 9 of the Main study.

The primary efficacy endpoint (change in HbA_(1c) from baseline [Month 6] to endpoint [Month 9]) was analyzed using an analysis of covariance (ANCOVA) model with treatment regimen and country as fixed effects and using the HbA_(1c) baseline value as a covariate. Differences between HOE901-U300 adaptable dosing regimen and HOE901-U300 fixed dosing regimen and two-sided 95% confidence intervals were estimated within the framework of ANCOVA.

All continuous secondary efficacy variables (except for change in variability of pre-injection SMPG) were analyzed using an ANCOVA model with treatment regimen and country as fixed effects and using the corresponding baseline value as a covariate.

Change in variability of pre-injection SMPG from baseline (month 6) to endpoint (month 9) is analyzed using an analysis of variance (ANOVA) model with treatment regimen and country as fixed effects.

Safety analyses were descriptive, based on the safety population.

Summary:

Population Characteristics:

A total of 110 patients with type 2 diabetes were randomized to the sub-study: 56 patients to the HOE901-U300 adaptable dosing interval regimen and 54 patients the to HOE901-U300 fixed dosing interval regimen; 110 patients were exposed to IMP (safety population). The mITT sub-study population (efficacy population) included 109 patients.

One patient (1/56, 1.8%) randomized to HOE901-U300 adaptable dosing intervals discontinued the sub-study prematurely and also discontinued the extension period of the main study (HOE901-U300 fixed dosing intervals: 0/54, 0%).

Demographics and patient characteristics at baseline (Month 6) were well-balanced between both regimen groups. The mean age of the sub-study population was 60 years; 35 of 110 (31.8%) patients were 65 years.

During the sub-study, on average 23.0% of the injections in patients in the adaptable dosing interval group were taken at the extreme intervals of <21.5 hours or >26.5 hours from previous injection versus 3.9% of injections in patients in the fixed dosing interval group. On average 13.5% of the injections in patients in the adaptable dosing interval group were taken in the intermediate interval (between 21.5-23 hours or between 25-26.5 hours after the previous injection) versus 8.2% of injections in patients in the fixed dosing interval group. Fewer injections by patients in the adaptable dosing interval group (63.4%) were taken within 23-25 hours after previous injection, compared with the fixed dosing interval group (88.0%).

A total of 34.5% of patients in the adaptable dosing group took less than 20% of their injections outside the 23-25 hours interval after previous injection and therefore around 65% of patients were considered to be compliant with the adaptable dosing interval regimen. In the fixed dosing interval group, 78.8% of patients took more than 80% of injections within 23-25 hours from the previous injection and therefore can be considered to be compliant with the fixed dosing interval regimen.

The compliance with either regimen was similar when intervals were calculated from the reference injection time as scheduled at the main study baseline.

Efficacy Results:

Primary Endpoint:

The LS mean change in HbA_(1c) from baseline (Month 6) to endpoint (Month 9) was similar in the groups of adaptable dosing intervals (0.22% [95% CI: −0.006 to 0.436]) and fixed dosing intervals (0.14% [95% CI: −0.099 to 0.380]) with the LS mean difference of 0.07% [95% CI: −0.169 to 0.318].

Secondary Efficacy Endpoints (Month 9):

-   -   FPG (adaptable dosing interval 1.40 mmol/L [95% CI: 0.624 to         2.177]; fixed dosing interval (1.18 mmol/L [95% CI: 0.350 to         2.015]; LS mean difference 0.22 mmol/L [95% CI: −0.634 to         1.070]).     -   Pre-injection SMPG, variability of pre-injection SMPG:     -   Adaptation of the injection intervals for HOE901-U300 resulting         in shorter and longer intervals than the regular 24-hour         interval may have an impact on the secondary efficacy endpoints         pre-injection SMPG and variability of pre-injection SMPG.         Therefore in addition to the overall analysis per dosing         interval regimen showing the mean of the average by patient over         up to 7 days prior to the visit, a breakdown of the SMPG data by         injection intervals will be presented in the CSR.

In both dosing interval regimen groups, the average basal and mealtime insulin daily doses remained stable during the 3-month comparative regimen period.

Safety:

During the 3-month comparative regimen period, hypoglycemia events, both overall and for each category of hypoglycemia, were reported by a similar percentage of patients in the HOE901-U300 adaptable dosing interval and HOE901-U300 fixed dosing interval regimens.

The percentages of patients with any TEAE (adaptable dosing intervals 15/56 [26.8%]; fixed dosing intervals 15/54 [27.8%]) or with a serious TEAE (adaptable dosing intervals 4/56 [7.1%]; fixed dosing intervals 5/56 [9.3%]) were comparable between the regimens.

No TEAEs leading to treatment discontinuation, leading to death, or linked to injection site reactions were observed in either dosing interval regimen during the 3-month sub-study period. One patient [1.9%] in the fixed dosing interval regimen had a TEAE linked to hypersensitivity reaction.

Conclusions:

The majority of patients in both dosing interval regimen groups followed the injection schedule as randomized and used either adaptable dosing intervals (HOE901-U300 once daily every 24 hours±3 hours on at least 2 days a week) or fixed dosing intervals (HOE901-U300 once daily every 24 hours). This allows a comparison of the two dosing interval regimens for efficacy and safety analyses.

The efficacy analyses in terms of HbA1c and FPG showed comparable results for the two dosing interval regimens.

Overall incidence of hypoglycemia (% of patients with at least one event) during the 3-month substudy period was similar in both regimens regardless of the category of hypoglycemia

HOE901-U300 adaptable dosing intervals and HOE901-U300 fixed dosing intervals were well tolerated during the 3-month comparative substudy period; no specific safety concerns were observed.

Taken together, according to the substudy results, no negative effects on main efficacy and safety endpoints were seen with occasional adaptations of injection intervals.

Methodology:

Multicenter, open-label, randomized, 4-arm parallel-group, comparative Phase 2 study comparing HOE901-U300 and Lantus in patients with type 1 diabetes mellitus. Patients were randomized to receive once daily basal insulin (HOE901-U300 or Lantus) and to the sequence of the injection time during study period A and study period B (morning then evening or evening then morning) with a ratio of 1:1:1:1. No formal sample size estimation was performed for this exploratory study.

Number of Patients:

planned 56, randomized 59, treated 59, Evaluated: efficacy 59, safety 59

Diagnosis and Criteria for Inclusion:

Inclusion criteria: Patients with type 1 diabetes mellitus; signed written informed consent. Key exclusion criteria: Age <18 years and >70 years; HbA1c >9% at screening; less than 1 year on basal plus mealtime insulin; Patients receiving >0.5 U/kg body weight basal insulin and patients not on stable insulin dose (±20% total basal insulin dose) in the last 30 days prior to screening visit; Hospitalization for diabetic ketoacidosis or history of severe hypoglycemia (requiring 3rd party assistance) in the last 6 months prior to randomization.

Study Treatments

Investigational Medicinal Products:

Tested drug: HOE901-U300; Control drug: Lantus

Formulations: HOE901-U300 was supplied as 300 U/mL insulin glargine solution for subcutaneous (SC) injection in 3 mL cartridges. Lantus was supplied as insulin glargine solution for SC injection 100 U/mL in 10 mL vials.

Route of administration: SC injection

Injection of HOE901-U300 was through the commercially available BD Ultra-Fine™ Short Needle Insulin Syringe with half-unit-scale. Injection of Lantus was to be done using commercially available BD insulin syringes:

-   -   for doses of 1-30 U insulin glargine: BD Ultra-Fine™ Short         Needle Insulin Syringe with half-unit-scale [8 mm (5/16″)×31 G];     -   for doses >30 U insulin glargine: BD Ultra-Fine™ Short Needle         Insulin Syringe [8 mm ( 5/16″)×31 G] with whole unit scale.

Dose regimen: Once daily injection in the morning or evening for 8 weeks during Period A then in the evening or morning respectively for another 8 weeks during Period B according to randomization.

Starting dose: Patients on Lantus or on once daily NPH or once daily insulin detemir prior to the baseline visit: the daily dose (U) of HOE901-U300 or Lantus was equal to the daily basal insulin doses on the day prior to the baseline visit. Patients on more than once daily NPH or insulin detemir prior to the baseline visit: 80% of total daily NPH or insulin detemir dose (=total daily dose reduced by 20%) on the day prior to the baseline visit.

Doses during the study: Dosing of insulin glargine given as HOE901-U300 or Lantus was done based on self-measured, fasting, pre breakfast plasma glucose levels (target range 80-130 mg/dL; 4.4-7.2 mmol/L), and taking into account also the presence of hypoglycemia. Minimum dose increments for the basal insulin were to be 1.5 U. Batch number: HOE901—U300: C1011129; Lantus: supplied by local pharmacies.

Non-Investigational Medicinal Products:

Short-acting mealtime (bolus) insulin analogue (glulisine, aspart or lispro).

Patients in both treatment groups were to continue with their mealtime insulin analogue during the study.

Mealtime insulin doses were to be adjusted based on SMPG data, including 2-hour postprandial plasma glucose results and the carbohydrate content of the meal to optimize glycemic control. The target range for 2-hour postprandial plasma glucose was <160 mg/dL (8.3 mmol/L). Bolus insulin doses could be reduced as basal insulin doses were increased.

Duration of Treatment:

Up to 16 weeks (8 weeks during Period A and 8 weeks during Period B)

Duration of Observation:

-   -   Up to 4-week screening (including a 2-week CGM training period);     -   2×8-week comparative efficacy and safety treatment period;     -   4 week post-treatment safety follow-up period after study         completion or permanent discontinuation of study treatment.

In total the maximum study duration was up to 24 weeks per patient

Criteria for Evaluation:

Primary Efficacy Endpoint:

Percent (%) of time in glycemic range of 80-140 mg/dL (4.4-7.8 mmol/L) during week 7 and 8 within treatment period A and during week 15 and 16 in treatment period B based on CGM.

Secondary Efficacy Endpoints:

Percent time above upper limit/below lower limit of glycemic range (% time in hyperglycemia/hypoglycemia).

The following secondary efficacy endpoints are not presented in this KRM: Diurnal glucose exposure; Diurnal glucose stability; Diurnal glucose variability; Mean and variation in glucose profiles; Average time within glycemic range in the last four hours of each dosing interval during 14 days of CGM usage in the last 2 weeks of the 8 weeks treatment period; Hyperglycemic AUC (Area below the CGM profile and above the upper limit of the glycemic range divided by total time period); and hypoglycemic AUC (Area above the CGM profile and below the lower limit of the glycemic range divided by total time period.

Further Secondary Efficacy Endpoints:

insulin dose; Not presented in this KRM: HbA_(1c), fasting plasma glucose (FPG), pre-injection SMPG, 7-point SMPG.

Safety

Hypoglycemia, occurrence of adverse events particularly treatment emergent adverse events (TEAEs) and serious adverse events (SAEs), injection site reactions and hypersensitivity reactions. Following information not presented in KRM: physical examination, other safety information including clinical laboratory data, vital signs and 12-lead ECG.

Statistical Methods:

The primary endpoint was analyzed using a linear mixed model with treatment (HOE901-U300 or Lantus) and period (treatment period A or B) as fixed effects, and patient as random effect. Adjusted mean estimates for each treatment with standard errors, the adjusted estimate of treatment mean difference with standard error and a 95 confidence interval for the treatment mean difference will be provided. The statistical test was two-sided tests at a nominal 5% significance level. The same model was used for secondary efficacy endpoints % time in hyperglycemia/hypoglycemia, diurnal glucose exposure, diurnal glucose stability and diurnal glucose variability. Other efficacy endpoints were descriptive. CGM related parameters were analyzed based on CGM population, non-CGM parameters were based on mITT population.

Safety analyses were descriptive, based on the safety population.

Summary:

Population Characteristics:

A total of 59 patients with type 1 diabetes were randomized to 1 of 4 arms: HOE901-U300 morning injection in Period A followed by evening injection in Period B (n=15), HOE901-U300 evening then morning injection (n=15), Lantus morning then evening injection (n=15), or Lantus evening then morning injection (n=14). A total of 59 patients were exposed to IMP (safety population) and included in the mITT and CGM populations (efficacy populations). One patient (3.3%) in the HOE901-U300 group and 3 patients (10.3%) in the Lantus group discontinued the study treatment prematurely. Demographics and baseline characteristics were balanced between treatment groups. The mean age of the study population was 44.2 years, 2 patients were 65 years or older. All patients were Caucasian. The mean BMI at baseline was 27.3 kg/m². The mean duration of diabetes prior to study start was 22.1 years. The median dose of daily total insulin was 0.565 U/kg body weight. Mean HbA_(1c) at baseline was 7.46%.

Efficacy Results:

Primary Efficacy Endpoint:

During the last 2 weeks of each 8-week treatment period, when the basal insulin dose was to be kept as stable as possible, plasma glucose measured by CGM was observed within glycemic range in 31.75% (LS mean) of time in the HOE901-U300 group and in 30.99% (LS mean) of time in the Lantus group. The LS mean difference was 0.75% [95% CI: −3.614 to 5.124].

Secondary Efficacy Endpoints:

During the last 2 weeks of each 8-week treatment period, percent time above the upper limit of glycemic range of 140 mg/dL (7.8 mmol/L) was comparable between treatment groups (58.24% in the HOE901-U300 group and 57.38% in the Lantus group in LS mean), so was the percent of time below the lower limit of 80 mg/dL (4.4 mmol/L) with 10.01% in the HOE901-U300 group and 11.64% in the Lantus group in LS mean.

Graphical presentation of average glucose based on CGM by hour of the day during the entire treatment period (FIG. 11) suggests smaller excursions in the HOE901-U300 group than in the Lantus group. The profile appears flatter with HOE901-U300 than with Lantus even more during morning injection period (FIG. 12) than during evening injection period (FIG. 13).

Overall, in the HOE901-U300 and in the Lantus treatment groups, basal insulin was similarly increased mostly in the first 6 weeks of the study and remained relatively stable thereafter (at baseline, mean daily basal insulin dose was similar in both treatment groups: HOE901-U300: 24.9 units; Lantus: 25.0 units; at week 16, HOE901-U300: 30.11 units; Lantus: 28.22 units).

Mean mealtime insulin daily dose was higher at baseline in the HOE901-U300 group (29.92 units) than in the Lantus group (23.69 units), but was comparable at week 16 (HOE901-U300: 27.34 units; Lantus: 26.31 units).

Safety Results:

During the on-treatment period, the percentages of patients experiencing hypoglycemia were generally comparable for overall and each category of hypoglycemia events (all hypoglycemia) in the HOE901-U300 group and the Lantus group. Consistently, similarity was observed in the hypoglycemia reporting between the following subgroups:

-   -   the morning and evening injection groups within the HOE901-U300         group;     -   the morning and evening injection groups within the Lantus         group;     -   the HOE901-U300 morning injection groups and the Lantus morning         injection groups;     -   the HOE901-U300 evening injection groups and the Lantus evening         injection groups;

The percentages of patients experiencing nocturnal hypoglycemia were consistently lower in the HOE901-U300 group than in the Lantus group regardless of morning or evening injection time. The favorable numerical trends in the HOE901-U300 group have to be interpreted with caution because of the small number of patients.

The percentage of patients with any TEAEs was higher in the HOE901-U300 group (24/30 [80.0%]) than in the Lantus group (19/29 [65.5%]). In the HOE901-U300 group, one patient experienced serious intestinal obstruction (unrelated to IMP) and another patient discontinued treatment due to pregnancy. No death was reported during the study. TEAEs linked to injection site reactions were observed in 2/30 [6.7%] patients of the HOE901-U300 group, and in 1/29 [3.4%] patient of the Lantus group. There is no concern regardingTEAEs linked to hypersensitivity reaction which occurred in 4/40 patients of the HOE901-U300 group and in 1/30 patient of the Lantus group.

Conclusions:

Plasma glucose measured by CGM was observed within glycemic target range (80-140 mg/dL or 4.4-7.8 mmol/L) for a similar percentage of time during the last 2 weeks of each 8-week treatment period in the HOE901-U300 group and in the Lantus group. Notably, this target range was tighter as compared with the ADA recommendation of 70-180 mg/dL (3.9-10.0 mmol/L).

In both treatment groups, the percent time spent above upper limit of glycemic range was higher (57%-58%) than the percent time spent below lower limit of target range (10-11%).

Overall, the percentage of patients with at least one event regardless of the category of hypoglycemia, during study was comparable in both treatment groups (HOE901-U300, Lantus) and for both injection times (morning or evening). The numerical trends in favor of the HOE901-U300 group for nocturnal hypoglycemia have to be interpreted with caution because of the small number of patients.

HOE901-U300 and Lantus, administered either in the morning or in the evening, were well tolerated during the study period, and no specific safety concerns were observed.

EXAMPLE 5: AN INVESTIGATIONAL NEW INSULIN U300: GLUCOSE CONTROL AND HYPOGLYCEMIA IN TYPE 2 DIABETES WITH BASAL INSULIN (EDITION II)

Aims:

An investigational new insulin U300 with an even flatter and more prolonged PK/PD profile than insulin glargine 100 U/mL (U100) is in clinical development. The phase 3 EDITION II study compared the efficacy and safety of U300 versus U100 in people with T2DM using a basal-insulin regimen in combination with OAD.

Methods:

In this multicenter, open-label, 6-month study, participants were randomized (1:1) to U300 or U100 once daily in the evening. Insulin dose was titrated to a target fasting plasma glucose (FPG) of 80-100 mg/dL. The primary endpoint was change in HbA_(1c) from baseline to 6 months and the 1^(st) main secondary efficacy endpoint in a hierarchical analysis was the percentage of participants with severe or confirmed (≤70 mg/dL) nocturnal (2400-0559 h) hypoglycemic event from week 9 to month 6.

Results:

811 participants were randomised [mean age 58.2 (SD 9.2) yr, duration of diabetes 12.6 (7.0) yr, BMI 34.8 (6.4) kg/m², basal insulin dose 0.67 (0.24) U/kg]. Baseline HbA_(1c) was comparable between groups; U300: 8.26 (0.86) % vs U100: 8.22 (0.77) %. U300 was non-inferior to U100 for change in HbA_(1c) [LS mean change −0.57 (SE: 0.09) % and −0.56 (SE: 0.09) %, respectively at 6 months; difference −0.01 (95% CI: −0.14 to +0.12) %]. No relevant differences were seen for FPG, 8-point self-monitored plasma glucose profiles and pre-injection plasma glucose. The percentage of participants with severe or confirmed nocturnal hypoglycemia was significantly lower with U300 vs U100 from week 9 to month 6 [21.6% vs 27.9%; relative risk (RR) 0.77 (95% CI: 0.61 to 0.99); p=0.038]. Over the 6-month treatment period, the incidence of any nocturnal hypoglycemia (% of participants with event) was lower with U300 vs U100 [30.5% vs 41.6%; RR 0.73 (95% CI: 0.60 to 0.89)] as was the incidence of any hypoglycemic event at any time of the day (24 h) [U300 71.5%; U100 79.3%; RR 0.90 (95% CI: 0.84 to 0.97)]. Severe hypoglycemia at any time of day was reported by 1.0% of U300 and 1.5% of U100 participants. No between-treatment differences in serious adverse events were seen.

Conclusion:

In people with T2DM using a basal-insulin regimen with OAD, U300 was well tolerated and as effective as U100 in blood glucose control. U300 was associated with 23% reduction in severe or confirmed nocturnal hypoglycemia from week 9 to month 6 compared with U100 and with a lower incidence of any nocturnal hypoglycemia event and hypoglycemia at any time of the day (24 h) over the entire 6-month study duration.

1 Synopsis

Phase of Development:

Substudy to phase 3 main study

Objectives:

Primary Objective:

To compare the efficacy of HOE901-U300 injected once daily every 24 hours and HOE901-U300 injected once daily at intervals of 24±3 hours in terms of change of HbA1c from month 6 of the main study (=baseline of sub-study) to month 9 of the main study (=endpoint of sub-study) in patients with type 2 diabetes mellitus.

Main Secondary Objectives:

To compare the safety of the two injection regimens for HOE901-U300 in terms of occurrence of hypoglycemia.

Methodology:

Patients randomized on HOE901-U300 and having received HOE901-U300 in the 6-month main study period are randomized 1:1 to administer HOE901-U300 once daily either every 24 hours (fixed dosing intervals) or every 24±3 hours (adaptable dosing intervals).

Patients on HOE901-U300 completing the 6-month main study period and meeting the eligibility criteria for the sub-study were eligible for the sub-study. No specific sample size was requested for the primary analysis that is descriptive.

Number of patients: Planned: up to 300 (150 pre treatment arm) Randomized: 89 Treated: 87 Evaluated: Efficacy: 86 Safety: 87

Diagnosis and Criteria for Inclusion:

Inclusion Criteria:

Completion of the 6-month study period in main study (Visit 10), Randomized and treated with HOE901-U300 during the 6-month treatment period (Baseline—month 6), Signed written informed consent for sub-study obtained.

Key Exclusion Criteria:

Patient not willing to use the adaptable injection intervals of 24±3 hours on at least two days per week; In the investigator's opinion, not able to comply with an adaptable dosing schedule; Health condition which precludes further participation of the patient in the study.

Study Treatments

Investigational Medicinal Product:

Tested drug: HOE901-U300

Formulation:

HOE901-U300 (insulin glargine 300 U/mL solution) is a sterile, non-pyrogenic, clear, colorless solution in a glass cartridge assembled in a pen-injector (prefilled, disposable pen).

Route of Administration:

subcutaneous injection

Tested Regimen:

Adaptable dosing intervals: HOE901-U300 administered once daily every 24±3 hours.

The injection time may have been adapted according to individual needs by up to 3 hours earlier or later than the daily reference injection time in the evening fixed at the start of the main study. The maximum intervals, ie, 3 hours earlier or 3 hours later than the fixed daily reference injection time was to be used on at least 2 days of the week at the patients' choice. The injection time fixed at start of the main study was to be maintained as reference time for the variation.

Control Regimen:

Fixed dosing intervals: HOE901-U300, once daily injection every 24 hours.

Patients continued to inject HOE901-U300 once daily every 24 hours at the injection time fixed at start of the main study.

Dose:

The dose of HOE901-U300 was to be titrated as needed to achieve or maintain fasting plasma glucose in the target range of 80 to 100 mg/dL (4.4 mmol/L to 5.6 mmol/L) without hypoglycemia. Changes in the insulin dose were based on fasting self-monitored capillary plasma glucose (SMPG) measurements.

Non-Investigational Medicinal Products:

Patients in both treatment regimens were to continue their oral antihyperglycemic background therapy during participation in the sub-study. Doses were to be kept stable throughout the study unless there was a specific safety issue related to these treatments. No other concomitant anti-diabetic treatments were to be used in this study.

Short term use (ie, 10 days at maximum) of short-acting insulin therapy (eg, due to acute illness or surgery) was not considered as rescue therapy. Rescue medication was considered as Non-investigational Medicinal Product.

Duration of Treatment:

The sub-study consisted of a 3 month comparative efficacy and safety treatment period starting at completion of the 6-month main study period and ending at completion of Month 9 of the main study.

After completion, patients on the adaptable dosing arm may have continued this regimen up to the end of the main study (Month 12). Patients injecting HOE901-U300 every 24 hours continued with their treatment regimen up to the end of the main study.

Duration of Observation:

The analysis period for efficacy and safety is the 3-month study period starting at Month 6 of the main study and ending at Month 9 of the main study. Results presented in the present KRM refer to this period.

Criteria for Evaluation:

Primary Efficacy Endpoint:

change in HbA_(1c) from baseline (Month 6) to endpoint (Month 9).

Secondary Efficacy Endpoints:

change in FPG (central laboratory) and change in daily dose of basal insulin, from baseline (Month 6) to endpoint (Month 9).

Safety:

Hypoglycemia (including nocturnal), occurrence of adverse events particularly treatment-emergent adverse events (TEAEs) and serious adverse events (SAEs), TEAEs leading to withdrawal, injection site reactions and hypersensitivity reactions. Following information not presented in KRM: other safety information including vital signs and overdose.

Statistical Methods:

For this 3-month sub-study, Baseline is defined as Month 6 of the main study; the Endpoint is Month 9 of the main study using last observation carried forward (LOCF) procedure.

The primary efficacy endpoint (change in HbA_(1c) from baseline [Month 6] to endpoint [Month 9]) was analyzed using an analysis of covariance (ANCOVA) model with treatment regimen and country as fixed effects and using the HbA_(1c) baseline value as a covariate. Differences between HOE901-U300 adaptable dosing regimen and HOE901-U300 fixed dosing regimen and two-sided 95% confidence intervals were estimated within the framework of ANCOVA.

All continuous secondary efficacy variables were analyzed using an ANCOVA model with treatment regimen and country as fixed effects and using the corresponding baseline value as a covariate.

Safety analyses were descriptive, based on the safety population.

Summary

Population Characteristics:

A total of 89 patients with type 2 diabetes mellitus were randomized to the sub-study: 45 patients to the HOE901-U300 adaptable dosing interval regimen and 44 patients to the HOE901-U300 fixed dosing interval regimen; 87 patients were exposed to IMP (safety population). The mITT sub-study population (efficacy population) included 86 patients.

A total of 40 (88.9%) patients randomized to HOE901-U300 adaptable dosing intervals and 38 (86.4%) randomized to HOE901-U300 fixed dosing intervals completed the 3-month comparative regimen period. 1 patient (2.2%) randomized to HOE901-U300 adaptable dosing intervals and 2 patients (4.5%) randomized to HOE901-U300 fixed dosing intervals discontinued the sub-study prematurely and also discontinued the extension period of the main study.

Demographics and patient characteristics at baseline (Month 6) were well-balanced between both regimen groups. The mean age of the sub-study population was 57.8 years; 16 of 89 (18.0%) patients were 65 years. 3 patients in the adaptable dosing interval regimen and 2 patients in the fixed dosing interval regimen were on insulin or insulin secretagogue started as rescue therapy during the main study period. No patient in either regimen group started rescue therapy during the 3-month comparative regimen period.

Compliance to Dosing Interval Regimens:

Compliance to dosing interval regimen was assessed taking into account the time interval between 2 consecutive injections and the time interval between an injection and the reference injection time as scheduled at the main study baseline.

During the sub-study, on average 28.04% of the injections per patient in the adaptable dosing interval group were taken at the extreme intervals of <21.5 hours or >26.5 hours between 2 consecutive injections versus 2.41% of injections in patients in the fixed dosing interval group, while 88.77% of the injections per patient in the fixed dosing interval group versus 53.09% of the injections per patient in the adaptable dosing interval group were taken within a 23-25 hour interval between 2 consecutive injections.

Evaluation of the time intervals between the actual injection and the reference injection times showed a higher percentage of injections per patient within the 23-25 hour interval in the fixed dosing interval group (mean 65.07%) compared with the adaptable dosing interval group (56.38%). In the adaptable dosing interval group 21.69% injections per patient were taken at intervals of 21.5-23 hours or at intervals of 25-26.5 hours (25.51% in the fixed dosing interval group). These data suggest that the majority of injections were taken up to 3 hours before or after the reference injection time, which was to be fixed as per protocol in the evening.

Based on the documented injection times during the week preceding the visits at Month 7.5 and at Month 9, a total of 47.5% of patients in the adaptable dosing group had 4 or more of their injection intervals outside the 21.5-26.5 hours interval after previous injection and therefore were considered to be compliant with the adaptable dosing interval regimen versus 2.6% of patients in the fixed dosing interval regimen. In the fixed dosing interval group, in 61.5% of patients all consecutive injection intervals were within 23-25 hours and therefore patients can be considered to be compliant with the fixed dosing interval regimen.

Efficacy:

Primary Efficacy Endpoint (Month 9):

The LS mean change in HbA_(1c) from baseline (Month 6) to endpoint (Month 9) was similar in the groups of adaptable dosing intervals (−0.12% [95% CI: −0.422 to 0.183]) and fixed dosing intervals (−0.25% [95% CI: −0.574 to 0.072]) with the LS mean difference of 0.13% [95% CI: −0.152 to 0.415].

Secondary Efficacy Endpoints (Month 9):

The LS mean change in FPG from baseline (Month 6) to endpoint (Month 9) was similar in the groups of adaptable dosing intervals (−0.46 mmol/L [95% CI: −1.521 to 0.609]) and fixed dosing intervals (−0.25 mmol/L [95% CI: −1.378 to 0.881]) with the LS mean difference of −0.21 [95% CI: −1.200 to 0.784].

In both dosing interval regimens, the average daily basal insulin dose remained stable during the 3-month comparative regimen period

Safety:

During the 3-month comparative substudy period, hypoglycemia events were reported in 16/44 (36.4%) of patients in the adaptable dosing interval regimen and 18/43 (41.9%) of patients in the fixed dosing interval regimen Each category of hypoglycemia event was reported by a comparable percentage of patients in both regimens. No event of severe hypoglycemia or severe nocturnal hypoglycemia occurred in either regimen.

The percentages of patients with any TEAE (adaptable dosing intervals 9/44 [20.5%]; fixed dosing intervals 11/43 [25.6%]) or with a serious TEAE (adaptable dosing intervals 2/44 [4.5%]; fixed dosing intervals 0/43) were comparable between the regimens.

No TEAEs leading to treatment discontinuationor to death, or linked to injection site reaction or to hypersensitivity reaction were observed in either dosing interval regimen during the 3-month substudy period.

Conclusions:

The evaluation of the duration of the injection intervals and the % patients with shorter or longer injection intervals than the regular 24-hour period suggests that the majority of patients in both dosing interval regimen groups followed the injection schedule as randomized and used either adaptable dosing intervals (HOE901-U300 once daily every 24 hours±3 hours on at least 2 days a week) or fixed dosing intervals (HOE901-U300 once daily every 24 hours). This allows a comparison of the two dosing interval regimens for efficacy and safety analyses.

The efficacy analyses in terms of HbA1c and FPG change from baseline (Month 6) to endpoint (Month 9) showed comparable results for the two dosing interval regimens.

Overall incidence of hypoglycemia (% of patients with at least one event) during the 3-month substudy period was comparable in both regimens regardless of the category of hypoglycemia.

HOE901-U300 given at either adaptable or fixed dosing intervals was well tolerated during the 3-month comparative substudy period; no specific safety concerns were observed.

Taken together, the substudy results suggest that occasional adaptation of the injection intervals by up to 3 hours earlier or later than the reference time for the once daily injection for HOE901-U300 had no effects on main efficacy (HbA1c) and safety endpoints, particularly hypoglycemia events, as compared with once daily injections at 24-hour intervals.
